On September 29, 2020, the U.S. Army Corps of Engineers, Bureau of Reclamation and Bonneville Power Administration released the joint Record of Decision for the Columbia River System Operations Environmental Impact Statement.

The joint ROD commits the agencies to implementing immediate and long-term actions related to the ongoing operations, maintenance and configuration of 14 federal dams that compose the Columbia River System.

The plan includes actions that support continued, reliable water resource benefits and balances the purposes of the federal dams while specifically supporting ongoing and new improvements for species listed under the Endangered Species Act. The signing of the joint ROD accomplishes a priority item in the Presidential Memorandum on Promoting the Reliable Supply and Delivery of Water in the West issued in October 2018.

A recorded virtual event commemorating the signing of the joint ROD, as well as the final EIS and joint ROD are available on the project website at
